Vehicle-mounted equipment

Abstract

A vehicle attachment includes a three-position blade mounted on a frame, the wings of the blade being connected Lo one another by a pivot shaft. Elements for attachment to a self-propelled vehicle are situated on one side of the frame, while brackets for connection, via sliders, to the wings of the blade are situated on the other side. Hydraulic cylinders for rotating the wings of the blade are symmetrically fastened to the frame, between the brackets. The rods of the hydraulic cylinders are pivotally connected to the pivot shaft of the blade wings, and the body of each hydraulic cylinder is connected to the frame by a pin. The pivotal connection of the blade to the attachment frame via sliders makes it possible to alter the angle at which the sections of the blade are mounted in a horizontal plane, with the wings of the blade being rotated in synchronism by the movement of the hydraulic cylinders.

1 . Vehicle-mounted equipment comprising a three-position blade mounted on a frame, wings of the blade being linked to each other by a pivot axle, and hydraulic cylinders for turning the blade wings, wherein each of the wings carries an upper guide and a lower guide attached to the same, the upper and lower guides embody sliders linked to the frame by axles, the hydraulic cylinders for turning the blade wings are attached to the frame and rods of the hydraulic cylinder are pivotally linked to the pivot axle of the blade wings.
